Well I have 20in wheels and 1 3/8" space from the spokes to the stock caliper. So I was not sure if I would need to replace the stock bolts if I did not need a spacer.
Also I was wondering if a 14in Baer rotor (made to fit a C6 vette) would work rather than the stock Z06 rotor because I already have these rotors on the car, so then the fronts would match the rears...

OK, so you still have the LS1 12" rotor. Then your 1 3/8" measurement is accurate. You might need some 1/2" spacers like Wesman, but I can't say for sure.

Yes, you can run a Baer replacement rotor, but I imagine it will be very expensive.

Alright, thanks for the info...I like the R1 Concepts rotors.

I was wondering if anyone had an opinion about how it would look to run to different rotors? Like the z06 on the fronts and Baer eradispeed on the rears...My friend says I'm just being **** about the slots going in opposite directions and that he would just run the Z06 rotors due to the cost difference.

well my price was. but what prices did you find. i paid right around 115 per rotor plus ship. and cheapest i could get z06 rotors was 250 for the set. and the DBA cool better and have a right and a left not two lefts

I was just browsing on tirerack and for anyone that's interested, they have the dba 4000 series 1 piece slotted rotors for $133 a piece and the centric blanks for $108 a piece. Just trying to throw more options out there for people.

After three pages of people asking about the installation, not one has asked how it performs?

So Wesman...how's the car stop now?

Honestly I haven't even tested them out fully yet. I've been trying to take it easy on them for the first few hundred miles. Some say break them in gently, other say bed the pads in by doing repeated 70-0MPH stops. They are stock GM pads, so I'm not sure whether they are required to be bed in or not.

I did take an 80 mile trip on Sunday, mostly highway and then city driving. On the way back though, I came off the highway at around 70MPH to the exit ramp, and I got on the brakes as I normally would. Initially, they felt about the same as the stock brakes. So I push the pedal slightly harder, and it felt like I just let the parachute out!! They really shed speed quickly and efficiently without any drama when you push the pedal with some intent.
